Lower frequency bands are often described as “beach-front property.One advantage of lower frequencies is that the signals have better penetration, meaning they pass through objects such as walls with less attenuation. This effect results in better in-building penetration.In trying to cover an area with the minimum number of sites, using 1800 MHz takes somewhere between 2 to 4 times as many sites as 850 MHz.

On other hand, It takes more sites to build out at 1800 MHz, but the increased number of sites simultaneously translates to much greater capacity. So even if it were to take three times as many sites for 1800 MHz as for 850 MHz, the 1800 MHz network will have three times as much capacity as the 850 MHz network, and the overall LTE network now has four times the total capacity as it did with just the 850 MHz band. Given that lower frequencies have such good propagation, one might wonder whether it might actually be a liability to use them in denser deployments with smaller cells. In other words, the signal in one cell might keep propagating into neighboring cells and cause excessive interference. Actually, an operator can prevent such excessive propagation by using down-tilt on the base station antennas. Thus the operator could ultimately build a high capacity network using lower frequencies and smaller cells.

The bottom line is that lower frequencies do offer advantages, but these advantages are often overstated. Most usage of mobile broadband networks will occur within higher population densities in which networks will have to be designed for capacity rather than coverage. In these scenarios, low and high frequencies offer almost equivalent performance.
